Title: Exhaust cleaning system e.g. for amphibious vehicles - has electrically driven blower with inlets from exhaust and fresh air
Inventor: SCHMITZ RUDOLF WERNER
IPC: F01N1/18
Filed: 1974-08-27
Abstract: The exhaust gas pipe of a vehicle internal combustion engine contains a filter which can also act as a silencer followed by a blower of the tangential impeller type. This has an inlet for exhaust gas coming from the filter and silencer and a second inlet open to atmosphere through which fresh air is taken in. The exhaust gases and the additional fresh air are mixed in the blower and discharged together through a common outlet for the cleansed gas. The concentration of carbon monoxide in the exhaust is in this way reduced. The blower is driven by an electric motor powered from the engine electrical system and is started as soon as the ignition is switched on.

Title: Colour ribbon in data printer - is fed perpendicularly across type line between upper and lower guides
Inventor: BOEHMER GEORG
IPC: B41J33/06
Filed: 1974-09-06
Abstract: The colour ribbon (1) in the data printer has storage rolls (2, 2) arranged respectively above and below the level of the type carrier (9). Guide elements (4, 5) support the ribbon for movement perpendicularly across the type line and through a path so as not to obscure the character last (7) typed in any one line or the text of any one previous line (8). The ribbon is movable laterally as for using two colours. The type carrier is pref. a disc with resilient type supporting arms. The arrangement avoids fouling by the ribbon of paper feed studs at the ends of the platen roll. s.

Title: Fully adjustable spring drive means for blackboards - comprises combination of swash-plate and leverage system allowing precise lift
Inventor: LEHSTEN SIEGFRIED
IPC: A47B97/06
Filed: 1974-09-12
Abstract: The spring drive for blackboards or wall charts comprises a combined swash-plate leverage system wherein one or more springs are suspended in the lever arm so that any desired height and lift can be achieved. The spring characteristic is compensated by a swash-plate on each side with one or more windings. The two spring balances are mounted in the middle of the lifting frame and are restricted in their movement up and down by stops. The drive means can be mounted adapted for adjustment on a full-length shaft of the spring drive, wherein the drive wheels and swash-plates are made of cast aluminium. If a welded construction is preferred then the cable groove can be formed by an angle iron bent over the corner.

Title: Disc boring and drilling tool - has disc peripherally grooved for equi-spaced cutters with intervening filler spaces (OE151275)
Inventor: HATCH HENRY PETER
IPC: E21B10/52
Filed: 1974-10-17
Abstract: Disc cutter for rock drills, boring tools etc., forms one of several discs mounted on a rotary plate serving as tooling for the machine. The annular body (10) of the disc has a peripheral groove (14) for a number of evenly spaced cutters (16) which are each brazed into the groove for securement purposes. Preferably the intervening spaces between the cutters in their mounting groove should be filled with filler substance. These fillers, suggestibly though not specified made from molten steel, form spacers between the individual cutters forming the disc edge and at the same time prevent drillings or abrasives from penetrating the groove areas between the cutters.

IPC: G03G9/093
Filed: 1974-11-29
Abstract: Prepn. of micro-encapsulated toners for electrographic reproduction, by (a) encapsulating a wax internal phase in a water-soluble polymer by coacervation in an aq. medium, dye and/or pigment being added to the internal phase or wall-forming material, (b) hardening the walls of the micro-capsules while in aq. suspension, by addn. of form-aldehyde, glutaraldehyde, Al chromate or Zn chromate, (c) coating the microcapsules with an outer duroplastic layer, by addn. of urea, formaldehyde and opt. resorcinol, melamine or methylated methylol melamine, and (d) modifying the duroplastic layer by addn. of an organic cpd. with >=1 -N(CH3)2, -NHCH3 or -NH2 gp., and (e) separating the water from the aq. suspension. Micro-encapsulation by coacervation gives narrow particle size distribution, simple equipment and pren. in aq. medium. The towers obtained have necessary tribo-electric properties, can be fixed by heat above at up to 100 degrees C, and are clean to handle. Use of a solid internal phase instead of liquid gives improved storage and handling properties.

Title: Assembling furniture from pre-fabricated components - by injecting plastics material into connecting and reinforcing zones
Inventor: TANTILLO GIORGIO
IPC: B29C45/14
Filed: 1975-03-04
Abstract: Articles of furniture are assembled from prefabricated, fitting, components, in a three-stage process, by arranging the components, in a 1st stage, in predetermined positions so that (part of) any given component lies closely to (part of) an adjacent component; fixing the components, in a 2nd stage, in such a way that the component parts partially define connectin and reinforcing zones for the components; and injecting or casting, in a 3rd stage, thermoplastics or hardenable material into these zones so as to result in a mechanical fixing of the components, eventually giving an integral structure consisting of the original components and the plastics. The process is quick and simple, and eliminates on the one hand laborious use of dowels, complicated joins etc., and on the other hand avoids capital-intensive investment in injection- and other moulding machinery.
Patent DE-2511429-A1 (DE)
Title: Multi purpose shower head - with axially displaceable perforated disc
Inventor: HERMANUS HEINRICH
IPC: B05B1/18
Filed: 1975-03-15
Abstract: The appliance consists of a shower head and a perforated disc (2) axially displaceable within the shower head (1) via a screw connection (7, 8). Disc and head have surfaces (9, 10) which extend in the axial direction of the connection, and which slide tangentially over each other, during the displacement. A circular groove (11) between the surfaces contains an elastic sealing and friction element (12), to seal the surfaces, and also to act against any torsion of the disc. The shower head and/or the disc have a circular shoulder (15, 16) to form an internal and external ring space (17, 18) in the shower head. When the disc is displaced into the shower head, the shoulder seals off the external from the internal chamber, and connects them, when an opposite displacement takes place. The supply channel (4) for the shower head opens into the inner chamber.

Title: Water mixing tap with hydrostatic control pressure - has push button operated pilot valve to close when pressure balance is established
Inventor: DENKENA KARL-HEINZ ING GRAD
IPC: F16K21/06
Filed: 1975-09-25
Abstract: A hot and cold water mixing tap has valve piston which is controlled by a hand operated push button and by internal hydrostatic pressure. When the tap is closed, the inlet water pressure is also applied to a hydrostatic pressure chamber on the opposite end of the valve piston. By operating the push button, a pilot valve opens, thus reducing the hydrostatic pressure. The inlet pressure thus lifts the valve piston off its seat, allowing the water mixture to flow to the outlet port. A throttled water flow gradually fills the pressure chamber so that with the help of a spring the tap closes automatically after a certain time.

Title: Keying circuit for radio transmitter - uses information presence or absence to key carrier on and off
Inventor: WEBER HEINZ-JUERGEN
IPC: H03C1/62
Filed: 1975-11-22
Abstract: The keying circuit for a radio transmitter, uses presence or absence of information for transmission to switch the carrier wave on and off respectively without loss of information. The information (N) is applied to the input of a first filter with rectifier (1) and to the input of a delay line (2). the delay line output is passed to a second filter with rectifier (3). The two filter with rectifier circuits remove noise and allow only the largest amplitude information signals to pass through. The outputs of the two filter and rectifier circuits are connected to the inputs of a gate (4) whose output is used to operate the transmitter keying relay.
